3. CD Error Correction

In the following tests, we check the drive's behavior when reading scratched / defective audio discs. The test discs used were the ABEX series from ALMEDIO.

- ABEX TCD-721R

Errors total Num: 45401
Errors (Loudness) dB(A) Num: 814 Avg: -64.0 dB(A) Max: -9.2 dB(A)
Error Muting Samples Num: 33 Avg: 202.5 Samples Max: 3327 Samples
Skips Samples Num: 0 Avg: 0.0 Samples Max: 0 Samples
Total Test Result 80.3 points (out of 100.0 maximum)

The total error count is extremely low at only 45,401. The maximum Error Loudness of -9.2 dB(A) is high and there were quite a few muted samples, but no skipped samples. The final test result score of 80.3 is extremely good.

- ABEX TCD-726

Errors total Num: 0
Errors (Loudness) dB(A) Num: 0 Avg: -174.0 dB(A) Max: -174.0 dB(A)
Error Muting Samples Num: 0 Avg: 0 Samples Max: 0 Samples
Skips Samples Num: 0 Avg: 0 Samples Max: 0 Samples
Total Test Result 100.0 points (out of 100.0 maximum)

Of late, it has been a rare site to see a drive attain a perfect score with this test disc. Extremely good results with both the ABEX test discs.

 

- CD-Check Audio Test Disc

The CD-Check Test Disc is a very useful tool for evaluating the Sound Reproduction / Error correction capabilities of a CD player. The disc offers a signal combination with disc error patterns to rate the drive's abilities to read music and reproduce it completely. Five tracks on the disc contain a sequence of progressively more difficult tests. These tracks are referred to as Check Level-1 through Check Level-5.

The tracks are reproduced through a software multimedia player (e.g. Windows Media Player). Each level is considered as passed, if the tone is smooth, continuous without interruptions, skipping or looping. The higher the Check Level passed, the more reliable the sound reproduction of the tested drive.
